Since you asked.  I once suggested "foo(&c) char c; { ... }"; this makes the
declaration in the callee match the syntax in the caller.  However, I have
since decided that the more general reference objects a la C++ are better,
since it allows you to write "lfunctions" that can be used on the left side
of an assignment (e.g. "x = pop(); ...; push() = x").  But as I mentioned in
another posting, "char *&c" is more consistent than "char &c" to declare a
reference.  (And it's probably better than adding a new keyword.)
